RPP series water jet vacuum pump adopts reinforced polypropylene plastic for one-time injection molding, with high mechanical strength, strong corrosion resistance, smooth surface, simple structure, and small volume. Among similar products, it has the characteristics of long service life, large exhaust volume, and high vacuum degree, and can be a good substitute for water ring vacuum pumps and reciprocating vacuum pumps. 

 This pump can pump corrosive gases at temperatures within 150 ℃, and can be used in series with steam jet pumps to achieve higher vacuum levels. It is widely used in industries such as chemical, pharmaceutical, textile, food, brewing, metallurgy, environmental protection, etc. It is mainly used in processes such as vacuum absorption, vacuum filtration, vacuum concentration, vacuum drying, vacuum transportation,vacuum deaeration and vacuum oxygenation. Our factory can provide complete sets of vertical and horizontal units. Users can also choose a series of supporting products such as corrosion-resistant pumps, check valves, and pipelines produced by our factory.

1、 In 1993, he was awarded the Hangzhou Science and Technology Progress Award. One of the earliest enterprises in China to produce polypropylene water jet vacuum pumps.

2、 Over 20 years, 35 experiments, 5 formula improvements, more durable

3、 In 2013, purchased a 5000g injection molding machine to ensure injection quality based on formula optimization

4、 Ceramic nozzles can be provided

You should know the difference:

1. The reasonable proportion of glass fiber content is related to the service life of the product, including strength and wear resistance.

2. In 2013, in order to ensure stable product quality, we invested over 1 million yuan to purchase the largest 7880 5000g injection molding machine in the industry. All accessories were processed by ourselves, reducing air holes in the products, increasing density, and ensuring the quality of injection molded parts.
